Another question:
In the parts bag, there is a short piece of silicon tube, 10mm OD, 6mm ID, 40mm long.
How to use this?

Thanks in advance,

If I'm not mistaken, that's the piece that goes over the long screw in the center of the battery hold-down. It's to keep the batteries from rubbing against the threads.

I cut mine in half, and stack it when using 4S packs (for 4S2P)...

Hi Darin,

Thank you so much for your quick reply.
As I use two 2S5000mAh packs, I cut the tube in half and it fits perfectly.
Thanks again,

Today I maidened my Impulse 31 with two ProTek2S5000mAh40C hard case packs.
Our club fellow Shiro took some pics.

In stock form can the impulse handle 2 3S lipos?

Hi everyone. first off, its great to be a part of this community. Lots of good info and tons of good reading.
I am not new to RC's but I am new to RC boats. I picked up an Impulse 31 as my first boat and I am glad I picked that over a Spartan. The boat runs good for an RTR with all stock electronics. All I had to do was to advance the timing to get a little more out of it. I dont have lots of money left to upgrade much on this boat although I will be trying out the Aquacraft 2030kv motor.
The only thing that I cant figure out is the occasional cutting out of the power. Its been like that from day one. Basically I run the boat for a few minutes and then it just cuts off for a minute or so and starts running again. The first thing anyone may suspect is the ESC thermaling. However at the end of a hard run I never got the motor or ESC hitting above 105-110.
The only other thing I can think of is signal loss to the radio and triggering the failsafe. I use my DX3S radio (with the proper firmware to work with marine receivers), the long antenna on the receiver is sticking out vertically and short one horizontally. Please keep in mind this problem happens only when the boat is around 3 or 400 feet away in the water.
Any suggestions to get rid of this annoying problem is appreciated.

The bullets on the motor to esc are only 3.5mm maybe they are getting hot and desoldering. I know that happened to me some years ago on a similar proboat motor and caused the same problem, even more so since you advanced the timing which would heat things up more.

Thanks for the advice. I never run 3.5mm bullets on any of my trucks. I was just waiting to get the new motor before I change them.
As a side note, speaking of bad solder joints, check this out

Ouch! Don't feel bad I just had a bad solder on one of my esc wires for the very first time. I was glad it was something so simple though instead of something expensive. Are you going to run the 2030kv UL-1 motor? I've got that as my spec motor for mine. It's almost as fast as my big motor with the prop I'm using on it now, should run great!

Will that UL-1 motor be a drop in replacement that would work well with the stock waterjacket and stock esc?

YES, perfect and great with the stock esc as well. Just gotta change bullet connectors.

I'm very curious of how that UL-1 motor runs vs the stock motor...

to much for the esc
may get a good run out of it, but I will possibly ruin the esc

About 4mph faster than the pb 1800kv with the same m545 prop and 11 degrees hotter.
